tag:old.nabble.com,2006:forum-1895Nabble - Octave2009-11-24T15:12:31ZGNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language. Octave home is <a href="http://www.octave.org/" target="_top" rel="nofollow">here</a>.tag:old.nabble.com,2006:post-26505023Re: Re: 3.2.4 call for patches2009-11-24T15:12:31Z2009-11-24T15:12:31ZTatsuro MATSUOKA-2Sorry if my reply is duplicate.

Good afternoon Renato, The approach I would take to your<br>
problem is as follows:<br>
<br>
# Matrix A is "freq", "impedance" and "phase", like this:<br>
<br>
# properly define the Matrix A<br>
<div class="im">A = [20.66, 12.32, 49.63;<br>
21.47, 13.75, 48.86;<br>

23.17, 18.43, 45.06;<br>
24.07, 22.61, 39.76];<br>
<br>
# I would like to get another Matrix, B, with the result of<br>
</div># multiplication of "impedance" and "phase":<br>
#<br>
# A(1,2) * cos(A(1,3)<br>
<div class="im"># A(2,2) * cos(A(2,3))<br>
# A(3,2) * cos(A(3,3))<br>
# A(4,2) * cos(A(4,3))<br>
# A(5,2) * cos(A(5,3))<br>

# 21.47 A(2,2) * cos(A(2,3))<br>
# 22.30 A(3,2) * cos(A(3,3))<br>
# 23.17 A(4,2) * cos(A(4,3))<br>
# 24.07 A(5,2) * cos(A(5,3))<br>
<br>
</div>freq = A(:,1); # extract column 1 data into freq vector<br>
impedance = A(:,2); # extract column 2 data into impedance vector<br>
phase = A(:,3); # extract column 3 data into phase vector<br>
<br>
B = [freq impedance .* cos(phase)]; # generate desired B matrix<br>
B<br>
clear freq impedance phase; # scuttle freq, impedance, and phase vectors<br>
# clearing variables helps to recover memory when needed<br>
<br>
Though not efficient in terms of storage and likely speed, extracting<br>
the data into named variables helps me to keep track of what each<br>
variable is. I am not an expert by any means.<br>
<br></blockquote><div><br>Basically all Octave expressions are reference-counted values, so storing an expression into a variable never (well, almost never) causes any extra copying. Hence your approach carries essentially no extra penalty.<br>

Jaroslav, I think it is safe to apply the first two to the 3.2.x<br>
branch. I'm not so sure about the third one though as it removes some<br>
variables from a class and changes at least one function signature,<br>
which might cause some binary compatibility problems.<br>
</blockquote></div><br>These don't apply due to unwind_protect changes. I think the second one reverts the first one, so maybe it would suffice to adapt the second one for 3.2.x. Does it make sense without also taking the third one?<br>

Please also apply this Ben's changeset to the 3.2.x source trees.<br>
Two lines shift occurred but patch itself was successful for print.m in 3.2.x branch.<br>

--------<br>
Bug report for Octave 3.0.4 configured for i686-pc-linux-gnu<br>
<br>
Description:<br>
-----------<br>
<br>
Saving an empty structure to a mat file and then loading it will result in a<br>
non-empty structure with no fields, which is different of the original<br>
variable (in particular it is non-empty). I generated the bug report in<br>
octave 3.0.4, but I was able to reproduce it in octave 3.2.3 as well.<br>
<br>
Repeat-By:<br>
---------<br>
<br>
First, let's create an empty structure<br>
<br>
octave:1> a = struct([])<br>
a =<br>
{<br>
0x0 struct array containing the fields:<br>
<br>
}<br>
octave:2> whos a<br>
<br>
*** local user variables:<br>
<br>
Prot Name Size Bytes Class<br>
==== ==== ==== ===== =====<br>
rwd a 0x0 0 struct<br>
<br>
Total is 0 elements using 0 bytes<br>
octave:3> isempty(a)<br>
ans = 1<br>
<br>
Now, let's save the structure and load the saved version<br>
octave:4> save test a<br>
octave:5> load test<br>
<br>
The structure now has one element, with no field :<br>
octave:6> a<br>
a =<br>
{<br>
}<br>
<br>
octave:7> whos a<br>
<br>
*** local user variables:<br>
<br>
Prot Name Size Bytes Class<br>
==== ==== ==== ===== =====<br>
rwd a 1x1 0 struct<br>
<br>
Total is 1 element using 0 bytes<br>
<br>
The difference with the original "a" is that it is not considered empty<br>
anymore :<br>
octave:8> isempty(a)<br>
ans = 0<br>
</blockquote></div><br><br>Thanks.<br><br>I've fixed this in the development sources:<br><a href="http://hg.savannah.gnu.org/hgweb/octave/rev/1fac51c5f83f" target="_top" rel="nofollow">http://hg.savannah.gnu.org/hgweb/octave/rev/1fac51c5f83f</a><br>

When loading, care is taken to preserve backward compatibility. In ascii, this is done by multiple keyword lookup (extract_keyword). In binary, the ndims is stored as a negative number, whereas len is positive.<br><br>For ascii format, this approach is even forward-compatible, meaning that older versions of Octave will be still able to read the new files. For binary, however, it is not. Worse yet, trying it will cause Octave to abort (negative nfields used to cause panic_impossible which I think was unnecessary, so I removed it). <br>
<br>Is this OK? Should any of these go to 3.2.4?<br clear="all"><br>-- <br>RNDr. Jaroslav Hajek<br>computing expert & GNU Octave developer<br>Aeronautical Research and Test Institute (VZLU)<br>Prague, Czech Republic<br>

<br>> Hi,
